Setting Up
Set the pressure on the Carrier Gas regulator-tee so that the gauge reads 25 psi.
Caution:
The maximum Carrier Gas pressure to the instrument must not exceed 29 psi.
Input pressures greater than 32 psi (2.2 bar) will damage the system.
Caution:
The maximum Compressed Air pressure to the instrument must not exceed
100 psi. Input pressures greater than 100 psi (6.9 bar) will damage the system.
Note: When using compressed gas cylinders, the tank must be replaced when the pressure falls below
300 psi (on the first stage of the regulator).
System Outgassing
Before the system can be used any air trapped in the gas lines and instrument must be purged out. After
purging the carrier gas supply system, the instrument must be out-gassed. After the initial purge residual
water vapor may still be present in the seals and void spaces within in the instrument. Out-gassing removes
this residual water vapor from the system.
To out-gas the system, follow these steps:
1.
Verify the Gas Supply Pressures are set correctly; see setting the Gas Supply Pressures on
page 2-9.
2.
Turn the instrument on.
3.
To properly out-gas the instrument a Test Cartridge must be mounted in each of the four
Test Stations. Mount a foil in four Test Cartridges. For more information on mounting a foil in
the Test Cartridge see the "User Guide" provided with your Test Cartridges.
4.
Load and Clamp a Test Cartridges in each of the stations. For more information refer to
Loading and Unloading a Test Cartridge on page 3-8.
5.
Let the system out-gas for at least one hour before starting a test.
